To all whom it may concern Be it known that I, JOSEPH J. OBninn, a citizen of the United States, residing at Washington, District of Columbia, have in vented certain new and useful Improves ments in Sanitary Drinking-Cups, of which the following is a specification.

This invention relates to improvements in sanitary drinking cups and the leading objectis to provide a simple sanitary drink ing cup adapted to be 1 ed as a postal card. Q 1

Another object of the invention is the construction of a sanitary drinking cup formed to hold a postal card; and adapted v to be mailed with said postal card.

A further object of the invention is the construction of a sanitary drinking cup adapted to fold perfectly flat when not in a drinking position and when pressure is released from its edge portions.

A further object of the invention is the,

construction of a sanitary drinking cup having a protectingflap held in place over the month thereof, whereby said mouth will be protected from contaminating influences.

A still further object of the invention is 1 the construction of an envelop body or strip formed into a series of detachable envelops. t A still further object of the invention 15 y the construction of an envelop or bag strip including a. series of detachable envelope or bags, each having a flap and thread formed out of the paper of which en velo or bag is composed and adapted to be etached from the envelop or bag and when detached to open the enivelop or bag.

the above and other 0 jects in view the invention consists in cer'ain combinw tions, constructions, and arrangements parts clearly described in the following speci cation and clearly illustrated in the accompanying d g: w mgs, in Which:

Fi re 1 is a active view showing the y drinkipg cup in a improved so- 2 is. a face view the postal card and the stamp window in the face wall of thedrinking cup.

.Fig. 3 is,a erspective view showing the back face of t e drinking cup and the pro- Fig. 4 is a horizontal sectional view s howini the drinliii'ng cup opened.

Fig. 7 is a perspective view of another modified form of the drinking cup. u i

F .'g. 8 is a detail corner of the modified form shown partly in Fig. 7.

Referring to the accompanying drawings illustrating the various forms of the invenh of the cup sectional view of a tion and particularly to Figs. 1 to -5, 5

denotes a strip of waterproof material, preferably transparent waxed paper or other fiber material, and which is folded to form,

a face Wall 6 and a back wall '4' and partitions 8 and 9. The partition 8 extends from the upper portion of the back Wall 7. and is connected at its bottom portion 'wi ththe portion 9, which has its upperedge portion extended to form the protecting flap 10, which is adapted to fold against the outer face of the Wall 7 or against the outer face of the wall 6. The upper edge portion of the wall 6 interned at 11 to protect this well against mutilation.

lWhen the strt 5 s folded it forms an inner and an on: 3 and three spaces for receiving mate 'ai. iii 11g strip 153 6 and the par seen the face wallseen the back The stiffening strip 12 is formed with,

creases or fold grooves 19., which extend in diagonally opposite directions from the a to form delivery iip 12". The walls 6 and 7, the partitions 8 and 9', and the stiflening strip 12 are held together by means of binding strips M, which are folded and compressed upon the edge portions of said Walls, partitions and strip. The binding strips 14 are preferably. made ofaluminu'm or other material protected against rusting centrai portion of the stifiening strip so as its or adapted to resist"corrosion. The side edge portions of thesealing flap 10am also secured by the binding strips 14, and are slightly weakened near the stripsl so that the flap 10 may be readily opened.

The space between the face wall 6 andthe partition 9'is normally open to receive the postal card, which is held frictionally beportions of the strip 5 may be folded, on'

themselves so that leakage of water will be more effectively prevented.

By applying pressure upon the upper and lower edge portions of the drinking cup, when the sealing and mouth protecting flap is opened the partitions 8 and 9 will be moved a art from each other so that the area of the water receiving space 5* will be 'lncreased, and the triangular corner portions of the stifl'ening strip will be bent inwardly so as to form a spout, whereby water can be safely directed over the lip 12" to the mouth of the drinker. On releasing pressure from the cpp it will immediately collapse, and by folding the flap 10 over the mouth of the cup said mouth will be pro tected.

The stiffening member 12 may be printed on for advertising purposes or may be formed into a postal card. When the postal card is left in its place between the wall 6 and the partition 9 it serves to stiflen said Wall and partition and, owing to its tend ency to resist bending, to promote the col lapsing action of the cup. The cup may be mailed with the postal card, like an ordinary envelop, and may be repeatedly used, with or without the postal card being in position. The drinking space let does not have communication with the postal card space, and in this way the postal card is preserved against contact with the water.

In Figs. 7 and 8 I show a modified form of the drinking cup, wherein the body of the cup is formed of rubberized silk. The material of the cup is folded to'form a U- shaped body, the rear wall 22 of which is extended to provide a jointfiap 20, which is cemented or otherwise united to the front wall 21, The front wall 21 isformed with relatively deep creases 21, arranged in diagonally opposite directions," and which provide a spout 23, as shown in Fig 7.

When a brightly colored postal cardis positioned between the partition 9 and the face wall 6 it will be visible through the partition 9, which is transparent, and the drinker will be able to study the postal card, with consequent pleasure and amusement. Any postal card may be' positioned between the face wall and the partition 9, and after the usual postal stamp has been placed on the card the combined card and drinking cup may be mailed. The sealin and protecting flap 10 is in no way disturbe When the recipient of the combined cup andpostal. card receives the combined article he may leave the postal card in its pocket, tear the sealing flap, and use the drinking cup.

Fig. 6 shows a drinking cup made of a single strip 15 of waterproof card board or material and folded into'a U, with one of its edges inturned at 16 and the other edge extended to form a sealing and mouth protecting flap 17. Binding strips 18 secure the side edge portions of the strip 15. The strip 15 is formed with creases 15, extending diagonally in opposite directions from the central portion of the wall 19 to the lower opposite corners thereof,

Fig. 7 shows a drinking cup made out of rubberized silk, andlhavingledge portions 20 of the face wall 21 comented or molded-to the back wall 22. The back vwall is formed with diagonal creases extending in opposite directions to form edrinking lip 23.

Having described my invention I claim 1. A drinking cup comprising a transparent waterproof body fdrmed into an inner and an outer U-shaped portion, one inner wall of the inner U-shaped portion being joined to one wall of the outer U-shaped portion, the side edges of the walls of the outer and inner U-sha-ped portions being joined to each other by a common sealing means on each side of the body, the space between the opposing walls of the inner U- shaped portion providing a compartment for water and the space between the terminal walls of the outer and inner portions providing a compartment for a postal card insertible therein, the two compartments being out of communication with each other, a postal card located between the terminal walls of the inner and outer portions, and

a scaling flap connected to the inner terminal wall and ,secured over the mouth of the water compartment.

A sanitary drinking cup comprising a sheet of water proof material bent upon itself to provide opposing side fiat walls, binding means holding the confronting side edge portions of the walls toward each other, each of the side walls being, formed with diagonal creases extending from the lower side portions thereof toward the upper central portion. thereof, the inner ends of the creases being spaced from each other to provide a spout forming portion, the side walls being normally flat and in contact with each other and being separable from each other by hand pressure exerted on the upper and lower edges of one end of the cup, whereby the upper side portions of each wall will be bent at an angle to the central portion of said wall and a three walled spout will be formed.

3. A sanitary drinking cup constructed of flexible water proof material and formed posing' spouts, the water discharging pasfrom each other by hand pressure on the op-.

posing edge portions of the cup, whereby the side walls will be shaped to provide ,op-

sages of which will be contracted by tinned pressure.

l. In COmbHIM'JOII, a sanitary drinking cup formed of water proof material and mo vided with normally flat walls separable from each other to provide a water holding compartment, a transparent element for holding a postal card on said cup, whereby the addressed face of the postal card will be ing the card from said forming with said cup a ing position' and movable visible for postal inspection without removcup; said element distinct pocket and being provided with an opening through which the postal stamp carried by the postal card will be accessible for postal cancellation without requiring the postal card to be removed from saidv oup, said postal card serving to stiffen said cup, and a. sealing flap secured over the mouth of the drinking cup to protect the interior of said cup durmg its transit through the mail, saidsealing flap being adapted to be detached from its coverover the mouth of the pocket containing the postal card.

In testimony whereof I aflix my signature inpresence of two witnesses JOSEPH J. OBRIEN. Witnesses:
